    • A method and apparatus for reinforcing the training received by an operator of a material handling vehicle (10) to maintain the operator's feet and legs in the operator compartment (11) includes a first (1) and second (2) photoelectric beam extending across the entry (19) to the compartment. When a deadman brake (22) is released by operating the floor switch (20) and the vehicle is commanded to move or is actually moving, the detectors (7, 9) sense the presence of objects extending through the entry. When objects are sensed, a vehicle brake can be applied, a visual (55, 57) or audio (59) sensor can be activated, or the detected fault can be stored in memory. The faults can be used by a supervisor to calculate an operator rating.

    • A lift truck power source includes a hybrid power supply including a storage battery, a capacitor bank, and optionally a fuel cell. The capacitor bank stores power produced during regeneration by either the truck traction system or the lift system and delivers current when current demand exceeds that delivered by the fuel cell. The storage battery or fuel cell acts as a main power supply to deliver current at a rate sufficient to power the lift truck. When the fuel cell is the main power supply, the storage battery stores power during times when current demand is less than that delivered by the fuel cell and delivers current at times when current demand is greater than that delivered by the fuel cell. When the storage battery is the main power supply, the fuel cell supplements the power delivered by the storage battery, and can also recharge the storage battery.
    • 一种起重车电源包括混合动力电源,包括蓄电池,电容器组和任选的燃料电池。 电容器组通过卡车牵引系统或电梯系统存储在再生期间产生的电力,并且当电流需求超过燃料电池传递的时间时传递电流。 蓄电池或燃料电池用作主电源,以足以为电梯提供动力的速率输送电流。 当燃料电池是主电源时,蓄电池在当前需求小于由燃料电池输送的时间时存储电力,并且在当前需求大于由燃料电池输送的时间时传递电流。 当蓄电池为主电源时,燃料电池补充由蓄电池供电的电力,也可以对蓄电池进行再充电。
